MMT In Gasoline
MMT is a manganese-containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emissions system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content
of gasoline may not be indicated on the gasoline pump,
therefore, you should ask your gasoline retailer whether
the gasoline contains MMT. It is even more important to
look for gasoline without MMT in Canada, because MMT
can be used at levels higher than those allowed in the
United States. MMT is prohibited in Federal and Califor-
nia reformulated gasoline.
Materials Added To Fuel
All gasoline sold in the United States is required to
contain effective detergent additives. Use of additional
detergents or other additives is not needed under normal
conditions and they would result in additional cost.
Therefore, you should not have to add anything to the
fuel.
Fuel System Cautions
CAUTION!
Follow these guidelines to maintain your vehicle’s
performance:
•The use of leaded gas is prohibited by Federal law.
Using leaded gasoline can impair engine perfor-
mance and damage the emissions control system.

STARTING AND OPERATING 373

CAUTION! (Continued)
•An out-of-tune engine or certain fuel or ignition
malfunctions can cause the catalytic converter to
overheat. If you notice a pungent burning odor or
some light smoke, your engine may be out of tune
or malfunctioning and may require immediate ser-
vice. Contact your authorized dealer for service
assistance.
•The use of fuel additives, which are now being
sold as octane enhancers, is not recommended.
Most of these products contain high concentrations
of methanol. Fuel system damage or vehicle perfor-
mance problems resulting from the use of such
fuels or additives is not the responsibility of the
manufacturer.
NOTE:Intentional tampering with the emissions control
system can result in civil penalties being assessed against
you.
Carbon Monoxide Warnings
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
•Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as
a garage, and never sit in a parked vehicle with the
engine running for an extended period. If the
vehicle is stopped in an open area with the engine
running for more than a short period, adjust the
ventilation system to force fresh, outside air into
the vehicle.
(Continued)
374 STARTING AND OPERATING

When you do switch fuel types it is recommended that:
•you do not add less than 5 gallons (19 Liters) when
refueling
•you drive the vehicle immediately after refueling for at
least 5 miles (8 km)
Observing these precautions will avoid possible hard
starting and/or significant deterioration in driveability
during warm up.
NOTE:
•Use seasonally adjusted E-85 fuel (ASTM D5798). With
non-seasonally adjusted E-85 fuel, you may experience
hard starting and rough idle following start up even if
the above recommendations are followed, especially
when the ambient temperature is below 32°F (0°C).
•Some additives used in regular gasoline are not fully
compatible with E-85 and may form deposits in yourengine. To eliminate driveability issues that may be
caused by these deposits, a supplemental gasoline
additive, such as MOPARInjector Cleanup or
Techron may be used.
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) And Gasoline Vehicles
FFV vehicles operated on E-85 require specially formu-
lated engine oils. These special requirements are included
in MOPARengine oils, and in equivalent oils meeting
Chrysler Specification MS-6395. The manufacturer only
recommends engine oils that are API Certified and meet
the requirements of Material Standard MS-6395. MS-6395
contains additional requirements, developed during ex-
tensive fleet testing, to provide additional protection to
Chrysler Group LLC engines. Use MOPARor an
equivalent oil meeting the specification MS-6395.

STARTING AND OPERATING 377

Engine Oil Viscosity – 2.4L Engine
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
the engine oil filler cap location, refer to “Engine Com-
partment” in “Maintaining Your Vehicle” for further
information.
Lubricants that do not have both, the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Engine Oil Viscosity – 3.6L Engine
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.The engine oil filler cap also shows the recommended
engine oil viscosity for your vehicle. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in “Maintaining Your Vehicle” for further informa-
tion.
Lubricants, which do not have both the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber, should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added To Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
